FiNi.KY, M.D., Associate Professor of Clinical Medicine, McGill University, Physician to the Mont- real General Hospital. Muscular atrophy in diseases of the nervous system is ahnost in- variably due to lesions affecting the cells of the anterior cornua or the nerves leading from them. (Jlinically such cases are known as atrophic paralysis, and form a di.stinct and well defined group. In cerebral disease, or in lesions of the fibres of the cord above the anterior cornua, atrophy is usually absent, although a moderate degree of wasting has often been noted in old standing cases of hemiplegia with contractions and is regarded as due to disease. Of late years, however, cases have been observed in which muscular atrophy has been early noted in limbs paralyzed from various forms of cerebral disease. Contrary to expectation, in some t)f these no changes have been found either in the anterior cornua or in the peripheral nerves. With the object of drawing attention to this condition I .submit the two following cases : Case I. Tumour of optic thalmus — hemiplegia — atrophy of inuscles of hand, forearm and leg — anterior cornua and peripheral nerves normal. Miss F.,rt>t. .55, was first seen .Tune 21st, 1892. For a month or five weeks past states that she has had pain over the anteriorpart of the scalp, intermittent, not severe and present chietly in the morning. She has also had pain in the back of the neck, most marked on rising from the recumbent posture. Aboiit the same time she began to experience diiticulty in walking, having a tendency to fall backwards and her knees giving way under her. She has vomited once or twice half an hour after her evening meal, without efTort or nausea. There has bci'n giddiness. Her friends state that she has been growing stout since her illness began, and that her memory has been failing for three months. Present Condition. — The patient is well nourished and somewhat stout. Intelli- gence is fair, but she exhibits no anxiety about her condition, and there is a ten- dency to laugh easily. In walking she moves the legs slowly and requires assistance. Tliere is a marked tendency to fall backward and to the left side. She is unable to use the hands even for eating. The arms and legs both show a marked degree of muscular power. The left labio-nasal fold is not so prominent as the right, and the movements in the lower part of the face are not (|uite so marked as on the right, but the upper muscles of the face move normally. Tl\e tongue is protruded straight. ' Read before the Canadian Medical Association, at Montreal, August 28, 1896. The senHc of position in nornuil iiiid IIutc Ih no iitivxiu of iinii.H and Icks.

Mental failure and weakness progressed rapidly, anns. — The pathological conditions in the brain vary both in site and character. In a considerable proportion of the cases tuinoiu's have been present, bi.t in others softening or hrenuir- rhage have e.\iste(i. Bremer and Carson' have collected six (including tlx'ir own") cases in which a tumour was present. Quincke" has reported a .sevt>nth aii-()ciated with considerable atroph}-, and in both my own cases a cerebral growth was present. In Babinski's' case a focus of softening in the centrum ovale minus, in the course of the psycho-motor Hltres was found. Eisenlohr, reports two cases, in one of wh'ch a recent, and in the other an old, heemorrhagic focus in the l)rain was found. The site of the lesions varies, but all involve some porti' n of the motor tract. A considerable lunnber of the cases of tumour have been in the motor cortex, l)ut in otiuirs the paralysis and ensuing atrophy have resulted from di.sease of the motor tract in the sub- cortical region and in the internal capsule. The optic thalmus has al.so been primarily involved with 'acts and medulla some- times occurs, an > Uh' r|(!prcc of atrophy is cit'tt'ii consitluralilc nii
